David Glacier Offset Video Radargrams and Doppler Width Map

v1.1 of this dataset contains offset video radargrams over Subglacial Lake Cheongsuk, David Glacier, Antarctica for the 2016–2017 (1617_OffsetVideo.zip) and 2018–2019 (1819_OffsetVideo.zip) field seasons in netcdf format, resulting 750 m window 250 m overlap Doppler width specularity maps in netcdf format (SpecularityMaps.zip), and seismic shot locations (SeismicKSS2_21-22.csv). Additional radargram processing information is available in the netcdf files. This data was used in "Mapping David Glacier Subglacial Water Routing with Airborne Ice-Penetrating Radar Doppler Spectra Width," currently in review.
